SerLCD pixel dimming

I wrote this code and it works but the pixel gets really dim when it is moving so fast is there a way to fix this.

#include <SoftwareSerial.h>
#include <serLCD.h>
#include "Game.h"
const int buttonPin = 3;
int buttonState;
int increment = + 1;
int increment1 = + 1;
int x = 1, c = 1;
int pin = 2;
int time = 50;
serLCD lcd(pin);
int num = 1;
byte dot1[8] = {

   Serial.begin(9600);
   lcd.createChar(1, dot1);

   lcd.createChar(3, dot3);
   lcd.createChar(4, dot4);
   lcd.createChar(5, dot5);
   lcd.createChar(7, arrow);
   pinMode(buttonPin, INPUT);
   lcd.clear();

 }
}
void loop() {
 buttonState = digitalRead(buttonPin);
 if (buttonState == HIGH) {
   lcd.setCursor(1, x);


   lcd.printCustomChar(c);
   delay(time);
   c = c + increment1;
   if (c < 2)increment1 = +1;
   if (c > 5) {
     c = 1;

     Serial.println(c);

 }
 else {

The smileys are supposed to be 8s.

They would show up correctly if you put your code in a 'code box'. --> How to use this forum - please read.

by box what do you mean

I mean the white area that now shows up in your original post since you have added the code tags.

Before:

else {
if (c == 3 && x == 8) {
arrow1();
lcd.setCursor(1, 1);
lcd.write(" Winner ");
delay(1000);
}
}

After:

else {
   if (c == 3 && x == 8) {
     arrow1();
     lcd.setCursor(1, 1);
     lcd.write("     Winner     ");
     delay(1000);
   }
 }

I looked at the how to use this forum thing after I asked " what do you mean"
